Changes in Serum Mineral Composition During Poxvirus Infection in Sheep and Their Lambs
2021
Başaran Karademir
Minerals have crucial roles in terms of vital function in the organism including hormones, enzymes, cell formation etc. Oxidative stress and related hormones, regarding infectious diseases, affect all functions of body including mineral taking, metabolism and excretion. The purpose of this study was to investigate the effect of the pox disease on blood minerals composition of sheep and lambs. This study was conducted on 20 healthy sheep, 20 poxvirus infected sheep and their lambs (Totally 80 subjects). One-shot blood samples from sheep and lambs were collected and serums were separated immediately. Serum mineral levels were analysed in the atomic absorption spectrophotometer. In general, the level of Cu in infected animals was higher than in healthy ones. Zn, Fe, Mg and Na levels of healthy animals were found higher than infected subjects. The difference between healthy and infected animal groups for serum Ca and K levels was not significant. Positive correlations were found between serum Zn, Fe, Mg and Na levels. However, a negative correlation was found between Cu-Zn and Cu-Fe pairs. Consequently, Cu, Zn, Fe, Mg and Na levels in serum, which are vital for animal organisms, showed significant changes in sheep and their lambs during poxvirus infection. To rapid healing or prevention of the diseases, mineral disorders must be corrected urgently.

Mansur Seymen Seğmenoğlu | Emine Baydan
This study aimed to determine and compare aluminum (Al), arsenic (As), cadmium (Cd), and lead (Pb) levels in conventional and organic milk, white cheese, and butter samples which are sold in the markets of Turkey. Within the scope of the study, totally 72 samples (36 for organic, and 36 for conventional) were collected, and analyzed between March 2010 and February 2011. After the samples were burned by microwave burning, element measurements were performed on atomic absorption spectrophotometer (AAS) device. As a result of the study, on the 49 samples (29 conventional, 20 organic) of the 72 collected product, element levels were determined above the limit of detection (LOD) (0.02 ppm). Pb and Al were the most common elements above the LOD. However, milk samples with a Pb level above the LOD still remained below the limit reported by the Turkish Food Codex Regulation for Contaminants. Since Turkish Food Codex Regulation does not have legal limits for Al, As, Cd and Pb for dairy products (cheese and butter), it was accepted as safe in terms of Al, As, Cd and Pb according to food limits in Turkish Food Codex and ADI values of FAO / WHO.

Olukayode Adediran Okunade | Olanrewaju Arinola
White and red cocoyam starches were physically modified by heat moisture treatment at 16, 24 and 32 % moisture levels. The functional and pasting properties of the modified and native starches were evaluated using standard methods. The swelling power at 60oC, water absorption capacity, oil absorption capacity, least gelation concentration, packed bulk density and loose bulk density of heat moisture treated white and red cocoyam starches ranged between 1.90 - 2.18 and 1.89 – 2.21; 1.00 – 1.80 ml/g and 0.80 – 1.60 ml/g; 1.40 – 1.80 ml/g and 1.20 – 1.40 ml/g; 8.00 – 10.00% and 8.00 – 10.00%; 0.51 – 0.62 g/ml and 0.54 – 0.64 g/ml; 0.41 – 0.51 g/ml and 0.43 – 0.53 g/ml respectively. For both white and red cocoyam starches, heat moisture treated starches at 16% moisture content level had the highest swelling power in the temperature range 60oC to 90oC; also starches treated at 32% moisture level had the highest water absorption capacity, oil absorption capacity, packed bulk density and loose bulk density. Red cocoyam native starch had higher peak, trough, breakdown, final and setback viscosity than white cocoyam starch. Heat moisture treatment generally increased the pasting properties of white cocoyam starch. The modification of red cocoyam starch at moisture levels of 16% and 24% reduced the pasting properties, however at higher moisture level, the pasting properties increased. These results suggest that moisture level of cocoyam starches influence their physicochemical properties during heat moisture modification; this will increase the array of food products in which the starches can be used.

2021
Abimbola Oluyemisi Adepoju | Ifeoluwa O. Opadiran
The management of forests, a source of livelihood in Nigeria, especially in the rural areas has received little attention in recent times. As a result, most of the forest dwellers who depend on these forests for survival are poor and are beginning to diversify their livelihood into off and non-forest activities as a relevant source of income. This study assessed participation in forest management practices, livelihood diversification and, the welfare of forest dwellers in Gambari Forest Reserve, Oyo State, Nigeria. Primary data, collected from 121 respondents using a multistage sampling Procedure were analyzed employing Descriptive Statistics, Logit, Tobit, and Ordinary Least Squares model. The decision to participate in forest management practices was significantly linked to gender, age, and membership in a forest association. Also, participation in forest management practices, gender, age, and credit accessibility significantly influenced livelihood diversification positively while farm size and monthly income had negative effects. The welfare of forest dwellers was found to be positively influenced by being a married indigene, having access to credit, participation in forest management practices, livelihood diversification, and monthly income while age, education, and market distance from homestead negatively affected the welfare of forest dwellers.

2021
Mohammad Akmal | Rabia Goher
Uncertain heat shock by a rapid increase in temperature particularly at the critical growth stage affects plant productivity. The study aimed to assess qualitative changes in wheat grains when plant exposed to high temperature shock (HTS) at starting anthesis for limited durations (48, 72 and 96h). Selected wheat cultivars (Pirsabak-2005, Pakhtunkhwa-2015, Pakistan-2013, DN-84, P-2, P-12 and P-18) were exposed to extending HTS effective from anthesis in the field covering plants within plastic tents for a limited duration. The experiment was conducted in 2017-18 and 2018-19 at the Research Farm, the University of Agriculture Peshawar, Pakistan in a randomized complete block design, in three replications. Temperatures inside and outside plastic tents were manually noted. Two years mean data showed significant effects of HTS on the wheat grain quality. Imposed HTS for 48, 72 and 96h resulted in a reduction on grain amylose by 23, 39 and 48% and wet gluten by 16, 25 and 36%, respectively when compared with the control (i.e. no HTS). Contrary to this, as compared to the control treatment an increase noted in the grain amylopectin by 7, 11 & 17% and in the grain N-content by 13, 28 & 41% with imposing HTS extending to a duration of 48, 72 and 96h, respectively. The study concluded adverse effects of HTS at the anthesis stage on wheat grain quality disturbing amylose and amylopectin ratios, which latter on brought changes in floor structure and gluten elasticity. However, cultivar did differ to respond to the changes but have the option to choose the best one.

2021
Abdalla S. Ammar | Mennat Allah I. Atwa | Dorreya M. Faress | Ashgan M. Ali
Food additives are used to protect food, increase quality and extend shelf life in many stages, from production to consumption of food. Colorants added by food producers to color food or to adjust the color to desired level are among the commonly used food additives. Considering today's developing production technologies, foods fade or discolor at various stages of processing, storage, and sale due to physical and chemical conditions such as heat, light, pH and oxygen. Colorants are used to regain these color losses, to enhance weak colors, to give color to the food that is actually colorless, and to win back the favour of customers by hiding low quality. Therefore, the most used food colorants in Canada, China, European Union, Mexico and United States of America were presented. The chemical name, chemical structure, common uses, acceptable daily intake (ADI), and toxicity literature of six most used artificial food colors were reviewed.

Rajib Sarker | Newton Chandra Paul | Md. Romij Uddin | Swapan Kumar Paul
The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh to investigate the influence of plant nutrient management on the yield performance of transplant Aman rice. The experiment comprised two Aman rice varieties viz. Binadhan-15 and Binadhan-16, and ten nutrient management viz. Recommended dose of inorganic fertilizer (RDF) Urea-TSP-MoP-Gypsum-ZnSO4 @ 150-110-70-60-5 kg ha-1, Cowdung @ 10 t ha-1, Poultry manure @ 5 t ha-1, Vermicompost @ 3 t ha-1 , 25% less than RDF + cowdung @ 5 t ha-1, 50% less than RDF + cowdung @ 10 t ha-1 , 25% less than RDF + poultry manure @ 2.5 t ha-1, 50% less than RDF + poultry manure @ 5 t ha-1, 25% less than RDF + vermicompost @ 1.5 t ha-1, 50% less than RDF + vermicompost @ 3 t ha-1. The experiment was laid out in a randomized complete block design with three replications. Binadhan-15 produced taller plants (97.86 cm), effective tillers hill-1 (6.28), grains panicle-1 (101.73), higher grain (3.58 t ha-1) and straw (4.99 t ha-1) yields compared to Binadhan-16. In case of nutrient management, 50% less than RDF + poultry manure @ 5 t ha-1 produced taller plants (101.1 cm), effective tillers hill-1 (7.07), grains panicle-1 (105.1) and grain yield (4.08 t ha-1). The highest grain yield (4.25 t ha-1) was recorded in Binadhan-15 fertilized with 50% less than RDF + poultry manure @ 5 t ha-1 and the lowest grain yield (2.28 t ha-1) was obtained in Binadhan-16 fertilized with vermicompost @ 3 t ha-1. So, it can be concluded that transplant Aman rice cv. Binadhan-15 fertilized with 50% less than RDF + poultry manure @ 5 t ha-1 appears as the promising practice to obtain the highest grain yield.

2021
Alevcan Kaplan | Alaattin Selçuk Ertekin | Esra Gündüzler
Leguminosae or Fabaceae is the third-largest flowering plant family and is important in terms of both food production and soil fertility. Wild Vicia species and the genetic diversity of the Southeastern Anatolia Region provide an invaluable resource for the improvement of cultivated temperate feed and legume crops. The rapid progress of technology in recent years has nowmade it possible to use modern techniques in phylogenetic studies and to examine plants in a greater detail using biochemical, cytological and molecular methods to supplement purely systematic studies. The use of molecular phylogenetic analysis is the most attractive alternative strategy for a more accurate identification of the species of the Vicia genus. In the current study, some Vicia L. taxa growing naturally in the Southeastern Anatolia Region were investigated using molecular phylogenetic analysis. Internal transcribed spacers (ITS) of nuclear ribosomal DNA were sequenced in order to study the phylogenetic relationships of Vicia L. taxa. Lathyrus inconspicuous L. and Lathyrus cassius Boiss. were used as an outgroup. The ITS area was determined to be approximately 479- 672 bp. The ITS sequences were submitted to the NCBI database and accession numbers obtained. The resulting tree clearly groups and separates the sect. Narbonensis, Ervilia, Peregrinae, Lathyroides, Vicia and Cracca species but was less able to distinguish species from sect. Hypechusa and Lentopsis. The data acquired were observed to be reliable in terms of solving the taxonomical problems of the Vicia L. taxa. The morphological distinctions are greatly supported by DNA sequence studies. The species-specific markers developed in this study are useful for early detection of targeted Vicia taxa and can act as a guide to the basic data required for the evolution of systematic breeding and conservation strategies, as well as for germplasm resources.
